Diffusional Kurtosis Imaging in the Diffusion Imaging in Python Project [PDF]

Frontiers in Human Neuroscience, 2021
Diffusion-weighted magnetic resonance imaging (dMRI) measurements and models provide information about brain connectivity and are sensitive to the physical properties of tissue microstructure.

Research on Diffusion Kurtosis Imaging of the Brain Based on Deep Learning

IEEE Access
Precise evaluation of the deviation of water molecule diffusion in the brain tissue from the Gaussian diffusion model is crucial for diagnosing brain disorders. Diffusion kurtosis imaging (DKI) is a technique that may accurately describe the non-Gaussian

Hierarchical Bayesian Modelling Improves Microstructural Parameter Mapping in Diffusion and Exchange MRI Data. [PDF]

NMR Biomed
Our hierarchical Bayesian modelling (HBM) technique is demonstrated in two neuroimaging diffusion MRI models. When compared with least‐squares (LSQ) minimisation, HBM increased the accuracy, precision, contrast‐to‐noise ratio and parameter map quality in simulated and human data. HBM also resolved local parameter variations associated with white matter

Widespread White Matter Microstructure Alterations Based on Diffusion Tensor Imaging and Diffusion Kurtosis Imaging in Patients With Pontine Infarction

Frontiers in Aging Neuroscience, 2021
Neurological deficits after stroke are closely related to white matter microstructure damage. However, secondary changes in white matter microstructure after pontine infarction (PI) in the whole brain remain unclear.

Brain Alterations Linked to the MPTP Mouse Model of Parkinson's Disease Uncovered by Diffusion Kurtosis Imaging and Magnetic Resonance Spectroscopy. [PDF]

CNS Neurosci Ther
In MPTP‐treated mice, DKI and 1H‐MRS revealed increased hippocampal and thalamic diffusivity with reduced striatal Glu/tCr and Glx/tCr at 24 h. By 72 h, cortical, striatal, and thalamic diffusivity rose, with partial hippocampal recovery. Elevated Tau/tCr and hippocampal metabolite alterations paralleled neuronal loss and gliosis, supporting DKI/1H‐MRS

Assessing Measurement Repeatability of a Novel Anisotropic Phantom for Advanced Diffusion MRI Models. [PDF]

Magn Reson Med
ABSTRACT Purpose Diffusion MRI is widely used to characterize tissue microstructure, but standardization remains challenging, particularly for advanced models or regions with crossing fibers. Phantoms provide controlled environments to assess measurement repeatability independent of biological variability.
